This theme component broke with some changes we made to category routing to allow for 3 levels of categories. If you’re running on 2.4 or later, this theme component is broken I’m afraid. I’ve moved it to #customization:theme:broken-theme for now.

The fix is quite complicated and not urgent since we now have the [Knowledge Explorer Plugin](https://meta.discourse.org/t/knowledge-explorer-plugin/130172) available.
